RSS(CH₂)_nSO₂Na (I; R = HO₂CCH₂CH₂, Ph, 4-MeC₆H₄; n = 3-5) were prepared as potential antiradiation agents (no data) in 53-85% yield by reaction of thiosulfonates II with RSNa. Studies of the disproportionation of I suggest that the principal process occurring is homolysis with light but heterolysis with heat. NaO₂S(CH₂)_nSSS(CH₂)_nSO₂Na (III; n = 3-5) were prepared in 73-85% yield by reaction of Na₂S with II. When heated in water, III rearranged to NaO₂S(CH₂)_nSS(CH₂)_nSO₂SNa.

Balavoine, Gilbert published the artcileThio glycosides as potential glycosyl donors in electrochemical glycosidation reactions. Part 1. Their preparation and reactivity toward simple alcohols, Related Products of catalysis-chemistry, the publication is Journal of Carbohydrate Chemistry (1995), 14(8), 1217-36, database is CAplus.

Constant potential electrolysis of several glycosyl donors such as substituted Ph 2,3,4,6-tetra-O-acetyl, benzoyl or benzyl-1-thio-β-D-gluco or galactopyranosides in dry acetonitrile in the presence of various primary, secondary or tertiary alcs. performed in an undivided cell, gave preferentially β-linked saccharides in moderate to good yields according to the nature of the protective groups on the sugar moiety. 2-Deoxy-2-phthalimido-1-thio-β-D-gluco derivatives gave the β-glucosides selectively in excellent yields. It was found, as expected, that substitution of the Ph group with methoxy or Me radicals facilitates the electrochem. glycosidation reaction by lowering the oxidation potentials of the corresponding thio glycosides.

Gonzalez-Perez, Jose A. published the artcileMolecular features of organic matter in diagnostic horizons from andosols as seen by analytical pyrolysis, Application of 2,4,6-Trimethoxybenzenethiol, the publication is Journal of Analytical and Applied Pyrolysis (2007), 80(2), 369-382, database is CAplus.

Andosols are usually formed from volcanic substrates, with thick A horizons high in organic carbon mainly in the form of stabilized humic fractions. The peculiar properties of these soils are, to large extent, affected by poorly crystalline materials like allophanes, imogolite and other Fe and Al oxyhydroxides that induce intense organo-mineral interactions which are considered to play a relevant role in OM protection against biodegradation as regards other soils developed under similar climatic conditions. Little is known about the mol. composition of this stabilized OM in a soil scenario often considered as an efficient C-sink in terms of C sequestration processes. Whole soil samples in addition to isolated humic and fulvic acids from organic A horizons of three soils with andic properties and one non-andic soil (Sodic Cambisol) from the island of Tenerife (Canary Islands, Spain) were analyzed by double shot pyrolysis-gas chromatog.-mass spectrometry (Py-GC/MS) in order to get some insight on the mol. composition of different structural domains of progressive structural stability. Clear differences were found between soils, both in thermal desorption and pyrolysis behavior of humic substances. In general the results suggest large yields of aliphatic (both alkyl and carbohydrate-derived pyrolysis compounds) pointing to high-performance processes of incorporation of aliphatic humic constituents in andosols probably favored by interactions with amorphous minerals, whereas in non-andic soils the latter are comparatively less stabilized and are removed in early pyrolysis stages as if they occurred as loosely joined, thermoevaporation-released products. In fact, compared to Cambisol, humic and fulvic acids from andic soils led to comparatively richer pyrograms and compound assemblages. The lack of similar amounts of these loosely joined, mainly aliphatic structures after thermal desorption of the whole andic soils indicate an origin for humic substances based on rapid sequestration of C-forms of recent (litter or microbial) origin.

Postma, Tobias M. published the artcileN-Chlorosuccinimide, an Efficient Reagent for On-Resin Disulfide Formation in Solid-Phase Peptide Synthesis, Category: catalysis-chemistry, the publication is Organic Letters (2013), 15(3), 616-619, database is CAplus and MEDLINE.

N-Chlorosuccinimide is described as a widely applicable on-resin disulfide-forming reagent. Disulfide bond formation was completed within 15 min in DMF. This strategy was successfully used in the synthesis of oxytocin and a regioselective synthesis of an α-conotoxin. Moreover, disulfide formation with N-chlorosuccinimide was found to be compatible with oxidation-prone methionine and tryptophan.
